h ar 3 3. 1? suppor e un nah 32 having its ends connectedto-the runnersfIn this arrangement, the driving; mechanism for the shaft 26 is disposed 'below the bottom Hand is thereby protectedfrom dust,'gravel and tlie like. The upper end of therotatable snaft 26 is pro.- vided with an oflset arm 33 defininga crank. The outer end" of this armisf'threaded to receive a nut 34 by means of which a bearing" member 35 is retained against axial movement of the crank arm but may rotate relative thereto,

A hub '36 of'a pan or basin generallyindicated at 37 slidably fits the bearing member 35. The bearing member and hub are respectively pro:- vided with abutment flanges 38' and 39 at their bottoms, the, hub being retained against removal from the bearingmember'rnerely by virtue ofthe weight of the hub and'pa'n associated therewith. The upper endof the hubis provided with a cap .4 w c e te d 'o r' t g'b afi nd ut thereby protecting" these parts against "gravel, dirt and the likewhich would sooncause theparts to' ea I 1 The pan or basin 3'? is "flared outwardly and upwardly from the lower end'of the hub 36, and at its periphery is provided'withan annular flange '41 which extends above a'nd'below the peripheral edge of the pan.

It will be observed that the upper end of the hub is disposed inthe dischargeop'ening15 of the hopper. With this arrangement,-when the shaft 26 is revolv'ed, the crank, 33 causes'the hub and pan associated therewith to move with a' gym- 'tory motion. This movementof the hub inlthe opening 15- greatly facilitates the dischar'geof material to' be separated fro'mthe' hopper, keeps-the material loose and free'so thatit will enter thepan without fouling. j Since the pan is supported for turning movement relative to the crank arm 33,"tlierejwould be a tendency of the panto revolve, about the crank arm during the operationoffthe separator.

To overcome this condition alug 421s provided on one side of the pan and connected by a chain :43 carrying'af weight 43'ato a" bracketsecured to the side of the housing. This chain enables the pan to gyrate'but'maintains the pan againstrotation around the crank arm 33. j V

"'I'hevibration or gyratory' movement of the pan 37'"caus es the material depositedtherein to be vigorously vibratedi This" action causes the 'metalliferous' or heavier particles of theimaterial to settle at the center of the'pan aroundthe'i'hub portion, whereas the lighter particles of material 41. Since this flange is inwardly spaced from the housing, the particles passing over the flange will fall to the bottom 17 and be discharged from the spout 21. The heavier particles may be easily recovered by removing the hopper which provides access to the pan 3'7 which may then be removed from the bearing 35, the chain 43 first having been detached. Although the pan containing the heavier particles of material may be easily emptied, it will be iobserved that theiseparating instrumentalities are so' constructedand-operate in such a manner that the device may, if desired,

be operated for several days without unloading.

; In'-,order that an operator may ascertain whether the mechanism is functioning properly "anddetermin when the pan has become suifi cientlyfllled. with heavier particles to warrant ope'nings -45 are provided in the housing. These openings are ordinarily kept -closed by means of are times when water maybe'used to washthe gravel. Therefore, any 'water which may flow overthe top edgeof the flange 41 will drip off the lower edge of the flange andwill not be carried along the bottom of thepanto the bearing portions of the machine.v From the foregoing; description; it will be apparent that this inventionprovides an improved separator which is admirably adaptedfor use in a portable or stationary device; a separator which is so constructed that the action of the separator instrumentalities' facilitates the discharge of the material from the'hopper, which is-s'i'mple in construction, eflicient in operation'fand which may be operated over a long period of time without its efficiency becoming impaired or itsparts being rendered ineffective I Now, itis of course, to be understood'that although I'have'described in detail the preferred embodiment'of my invention, the invention is not to be" thus limited but only in so far as defined by the scope and spirit ofthe appendedclaims.
